The shadow education secretary is following medical advice and is self-isolating after developing symptoms that have “gradually got worse”.

It follows the news that Prime Minister Boris Johnson has tested positive for coronavirus but he has pledged to continue leading the national fight against the outbreak from Number 10 Downing Street.

Anyone showing signs of coronavirus, which include a temperature and a persistent dry cough, have been instructed to self-isolate for seven days, and everyone living in their household should do the same for a two-week period.

I am now in self isolation as l have the symptoms of #Coronavirus they started last night and have gradually got worse. I will be a bit quieter than usual but will still be keeping in touch with people as best as l can. #KeepSafe everybody and remember #StayHomeSaveLives
